I want to add an LNA to the 7021 RFIN pin. Do you have any related integrated circuits and application circuits? 50 ohm impedance is required. Thank you

It's best to open a query regarding LNA part suggestions on https://ez.analog.com/amplifiers/. As per resources for ADF7021-N, the application note "RF Port Impedance Data, Matching, and External Component Selection for the ADF7020-1, ADF7021, and ADF7021-N" will help you. This does not have application circuits for adding external LNA, nor LNA IC suggestions. However, impedance matching is essential in RF design and this is a comprehensive guide in impedance matching. If you really need in-depth help with your design/ application, please consult your local FAE to get your project going.
